  • Brick Masonry Important Qualities
    • Grades:
      • Weatherability: evaluates how the bricks will hold up to weather exposure (freeze/thaw, rain, etc.)
      • Facing Bricks: evaluates the uniformity of shape, dimension, texture & color
    • Provides for full bearing
    • Seals between masonry units
    • Adheres / bonds masonry units
    • Aesthetics ( 20% of wall area)
